I was gonna make a list like this, but you pretty much got it covered, haha. I'd mention Steins;gate and Spice&Wolf just because I like them and they are so well done. This list is what people should definitely check out.

I think the newest addition I would put on this list is Kill La Kill, but although I personally love Kill La Kill, I can at least understand why people would disagree here. I know there are plenty of people who find it to be completely unwatchable and extremely over-hyped. My advice to people would be that it's one you have to at least try. Watch the first three or four episodes and see if you feel like sticking with it.

In any case, these are just animes that I personally really love and would recommend to others. We can all argue about how they affected the industry and their actual "worth" another time
